Essays and tutorials on computer vision in the real world, the physics of the cosmos — black holes, string theory, information — and how to build systems that see. Written in first person by Ashwin Rajendraprasad.
Every imaging system — an eye, a telescope, a phone camera, a computer vision pipeline — runs into the same wall: physics sets a hard limit on resolution. A tour of where that limit comes from.

Build a working 478-landmark face tracker in a single HTML file — MediaPipe from a CDN, getUserMedia, and a canvas overlay. No npm, no bundler, working code included.
The gap between a computer vision demo and a production system is where most projects die. Lessons from two decades of shipping perception systems to real users in the real world.
